Well, you've spent enough on the Andra II's to want to hear what they can REALLY do. I use Purist Dominus Rev. B bi-wire on them, and the result is simply amazing. Used, Dominus is just barely affordable. The next best thing I've found is HMS Gran Finale Top Match bi-wire, which is a a warm and detailed cable and a great match in terms of complementing the qualities of the speaker, at a very reasonable price, but can't match the Dominus (not that anything I've ever found does). Whatever you use, bi-wiring makes a substantial difference--jumpers don't seem to work well on the Andra II's, no matter how good the cables are.
